`3/12-9/12`

Simplify 9 5/6 -4 3/8+2 7/12

Analyze the roots of the following equations: 2x^3-9x2+12-(9//2)=0. 2x^3-9x2+12 x-3=0.

Find the diffrence: (i) (5)/(9)-(2)/(9) (ii) (11)/(12)-(7)/(12)

Replace * by in each of the following to make the statement true: (-6)+(-9)*(-6)-(-9) (-12)-(-12)*(-12)+(-12)

Which one of the following is true? 1/2<9/(13)<3/4<(12)/(17) (b) 3/4<9/(13)<1/2<(12)/(17) (c) 1/2<3/4<9/(13)<(12)/(17) (d) 1/2<9/(13)<(12)/(17)<3/4

int_(3)^(9)(root(3)(12-x))/(x3+12-x3)dx

cos(pi/12)+sin^2((3pi)/12)+sin^2((9pi)/12)+cos((11pi)/12)=...

Verify the following: (i) (-12)/(5)+(2)/(7)=(2)/(7)+(-12)/(5) (ii) (-5)/(8)+(-9)/(13)= (-9)/(13)+(-5)/(8) (iii) 3+(-7)/(12)=(-7)/(12)+3 (iv) (2)/(-7)+(12)/(-35)=(12)/(-35)+(2)/(-7)
